'Distorted by galvanising' ?
In 1999 I arrived at a Lotus dealers in the North West to collect my brand new un-galvanised lotus chassis .
I got out of my car to see 'a' Lotus Elan chassis being knocked around the car park with a hide mallet.
It was eventually put up against the curb stones in the car park where one of the two mechanics measured from front to back , from corner to corner , the second mechanic then stood on the backbone of the chassis before the first set about hitting the rear upright at one corner of the chassis before repeatedly measuring it again and again.
After watching this process for sometime I went into the show room to state that I had arrived to collect my new Lotus chassis then added that I hoped that the chassis being physically abused in the car park was not mine.
An embarrassed sales assistant assured me that it wasn't mine, then followed a flurry of activity and a chassis without scratches to both paint and metal work was delivered to my waiting transport.
I'm very much aware that the galvanising process can cause 'some' distortion but after witnessing the chassis being beaten into submission and other owners Lotus chassis's both galvanised and un-galvanised arriving very much distorted I would suggest that back in 1999 to around 2005 ish whoever was manufacturing the chassis's was using either a worn jig / tooling and / or the jig wasn't correctly set up in the first place.
One person I know received a new Lotus chassis so badly distorted he returned it to the supplier then promptly ordered a new Spyder item. Not my personal choice but when finished his Elan drove and handled fantastically and continues to do so.
How many different manufacturers are producing the Lotus chassis's now, from the different examples I have seen this last 12 month's it's definitely more than one ?
What I'm suggesting is that the galvanising process was/is still being used to excuse some of the bad manufacturing techniques previously used.
I speak as a qualified and experienced welder , fabricator of many years.
Spyder V's Lotus chassis?
Comes down to driver ability ,personal preference and the person with the biggest balls to drive an Elan on it's limit, In my humble opinion of course.

It?s pretty impossible to answer your question properly. Most competition formula insist on original equipment as available before a certain cut off date, so in most cases that precludes the use of a Spyder Space frame chassis. Therefore it?s unlikely that you will ever find two GTS 26R clones that are identical apart from the chassis used.
Supposedly the Spyder Spaceframe is stiffer than the standard folded metal item, but it?s not clear to me if this is necessarily a good thing. The modifications over a standard folded chassis carried out to the 26R style chassis most likely address the stiffness difference.
The history of the Spyder Spaceframe stems from a threatened lawsuit when Lotus finally woke up to the fact that they were losing valuable sales for spares that they previously couldn?t be bothered with until they saw how many Spyder were making for an eager public wanting to keep their Elans on the road. The result was a redesign that allowed Spyder to continue producing replacement chassis which they marketed as an improvement over the original pattern which perhaps was an important fact back in the days before ?the cult of originality? gained momentum.
The lawsuit is long gone as is the patent for the folded chassis. Spyder will make a folded chassis for you if you want one with the benefit that you can order it 2k low baked to your colour choice, and it will be guaranteed to be straight and not distorted by galvanising.
Sandy,
Bring your car to the UK and stay with me as my guest, we will do some track days and test your theory about being able to keep up!
